(B) The formula for the refractive index $n$ of a prism is given by $n = \frac{\sin((A + \delta_{\min})/2)}{\sin(A/2)}$.Given that the angle of minimum deviation $\delta_{\min}$ is equal to the refracting angle $A$, we substitute $\delta_{\min} = A$ into the formula.$n = \frac{\sin((A + A)/2)}{\sin(A/2)} = \frac{\sin(A)}{\sin(A/2)}$.Using the trigonometric identity $\sin(A) = 2 \sin(A/2) \cos(A/2)$, we get $n = \frac{2 \sin(A/2) \cos(A/2)}{\sin(A/2)} = 2 \cos(A/2)$.Since the refracting angle $A$ of a prism must satisfy $0 Therefore, $0 Multiplying by $2$, we get $0 However, for a physical prism, $A$ is typically small or less than $180^{\circ}$, and $n > 1$. Thus, $1 < n < 2$.

For a transparent prism, if the angle of minimum deviation is equal to its refracting angle, the refractive index $n$ of the prism satisfies.
